Need a Radio for the 90, it has some plugs of sorts so I presume it had one from the dealers when new.
It's a 1990 Defender so hopefully I can get one and just plug it in, got three CD stereos but no plugs to fit them to Landy
Take a photo of the existing wiring and blocks. It should have an ISO block in there it might be as easy to get an adapter to convert it to the ISO and run a CD player you already have.
